Description
Technical field
The present invention relates to a kind of foliage-spray processing for the planted corn of cadmium pollution soil, reduction corn kernel cadmium content
Corn cadmium agent is dropped, belong to arable land Heavy Metal Pollution Control technology and Technique for Corn Cultivation field.Specifically a kind of corn
Cadmium agent is dropped, is formed by drop cadmium ingredient, adhesive, colorant and auxiliary agent by crushing, mixed preparing, is planted suitable for cadmium pollution soil
The foliage-spray of corn reduces corn kernel cadmium content.
Background technique
Cadmium is a kind of poisoning metal element, into human body after can gradually be accumulated in the systems such as liver, kidney, bone, lung, cause
The damage of these systems.Cadmium slow poisoning Symptoms are hyposmia, fatigue, hemoglobin reduction etc., severe poisoning meeting
Cause " Itai-itai diseases ", even occur complication and it is dead.In the l2 kind hazardous substance that United Nations Environment Programme in 1984 proposes,
Cadmium is listed in first place.Ore extraction, metal smelt, chemical industry manufacture etc. modern industries rapid development, caused soil, water body,
Atmosphere cadmium pollution gradually aggravates.According to incompletely statistics, the whole world is up to more than 20,000 tons into the cadmium in soil every year.
Corn is one of absorption, the very strong staple crop of cadmium.It is reported that China is reached by the cultivated area of cadmium pollution
27.86 ten thousand hm2, 15.2% corn kernel cadmium content is exceeded.However, there are no cause enough attention so far for corn cadmium pollution.
Currently, the method that China administers the cadmium pollution of large area arable soil, mainly there is phytoremediation and chemical passivation method.
Although phytoremediation is economical, environmental protection, it is administered, and period is very long, corn field can transitory loss production capacity, be not suitable for China
The national conditions having a large population and a few land.The approach such as soil Eh or pH are adjusted by the methods of soil application lime reduces the biology of Cadmium in Soil
Validity, to control the chemical passivation method of corn kernel Cd accumulation, although quick, effect is obvious, its dosage is too big, cost
It is excessively high, and can have a negative impact to soil quality, it is difficult to it is widely applied.
Therefore, research and development drop cadmium effect is obvious, quick, dosage is few, at low cost, to arable soil environmental quality without bad shadow
Cadmium method drops in loud corn kernel, be current China's corn safety production should be paid much attention to, idea solves main problem it
One.
Summary of the invention
It is an object of the invention to：For the above-mentioned main deficiency of the prior art, with novel drop cadmium ingredient and maize leaves
Face sprays technology, provide it is a kind of have the characteristics that drop that cadmium is obvious, production is easy, easy to use, low in cost, environmental-friendly,
Cadmium agent drops in the corn suitable for corn foliage-spray, reduction corn kernel cadmium content.
The invention is realized in this way：It is drop cadmium ingredient with calcium acetate and zinc chloride, passes through with adhesive, colorant and auxiliary agent
It crushes, mixed preparing is to get corn drop cadmium agent.
（1）The drop cadmium ingredient is calcium acetate and zinc chloride；Dosage is the 18%~23% of gross mass；
（2）The adhesive is carboxymethyl starch；Dosage is the 3%~9% of gross mass；
（3）The colorant is alkalescent light green；Dosage is the 0.03%~0.08% of gross mass；
（4）The auxiliary agent is sepiolite；Dosage is the surplus of gross mass to 100%.
Production method of the invention：
According to recipe requirements, drop cadmium ingredient, adhesive, colorant and auxiliary agent are crushed to 200 mesh or more with common grinder respectively,
Then each component is put into V-arrangement mixing machine, is sufficiently mixed uniformly, then be crushed to 450 mesh or more with micronizer, according to life
Production standard drops cadmium agent with quantitative package is required to get corn.
Application method of the invention：
The present invention is suitable for the foliage-spray of the planted corn of cadmium pollution soil, reduces corn kernel cadmium content.In use, according to jade
Rice drop cadmium agent:Water=1:155~175 mass ratio is watered, and is made into suspension, respectively the tasseling stage of corn growth, spinning the phase,
Ripe initial stage carries out a foliage-spray.Corn sprays corn drop cadmium dilution agent 21~23Kg of liquid every time per acre, preferably
22Kg。
Mechanism of action of the invention：
The present invention sprays application on maize leaf, under the action of adhesive contained drop cadmium ingredient energy uniform adhesion in blade surface,
And gradually absorbed by blade, into plant in and be transmitted to entire plant, resistance control maize root system absorb cadmium in soil,
Accumulation of the resistance control cadmium from maize root system to the transhipment of plant top and cadmium in corn kernel, contains to reduce corn kernel cadmium
Amount.Although corn is gramineous crop, blade area is big, is Dry crop, and physiological property is different with rice, therefore,
For dropping the composition and dosage of cadmium agent, content, the fineness for dropping cadmium composition are different, in terms of be also different
, these need to carry out scientific research and test.
The present invention is the Ministry of Agriculture, Ministry of Finance's scientific research special " Hunan arable land heavy metal pollution recovery technique optimizes and integrates " etc.
The master of project grinds one of content.Pot experiment and field production test proof by more than 2 years：The present invention is applied to cadmium pollution soil
The corn that earth is planted drops cadmium agent according to corn:Water=1:155~175 mass ratio is watered, and suspension is made into, respectively in corn
The tasseling stage of growth, spinning phase, ripe initial stage carry out a foliage-spray, and corn sprays corn drop cadmium dilution agent liquid every time per acre
21~23Kg, corn kernel cadmium content averagely reduce by 40.3%~60.8%.The present invention does not influence the normal growth of corn, to soil
Environmental quality has no adverse effects.
Compared with prior art, main advantages of the present invention：
（1）Simple production process of the present invention, easy to use, quick, drop cadmium is obvious, does not influence the normal production energy of corn field
Power is easier to be widely applied；Existing phytoremediation technology can be overcome to administer, and the period is very long, and corn field can transitory loss production
Ability is not suitable for the national conditions that current China has a large population and a few land, it is difficult to be widely applied equal major defects.
（2）Usage mode of the invention is foliage-spray, and dosage is few, at low cost, to agricultural land soil without obvious adverse effect；
The technologies such as soil application lime can be overcome control dosing existing for the chemical passivation method of corn kernel Cd accumulation it is too big,
It is at high cost, the major defects such as may have a negative impact to agricultural land soil.
（3）The country there is no special corn drop Cadmium treated agent, the drop Cadmium treated agent master of other crops such as existing rice at present
It to be aqua, emulsion, when preparation must add the auxiliary elements such as emulsifier, dispersing agent, antifreezing agent, preservative；And the present invention is
Pulvis, it is not only low in cost, but also avoid a large amount of pollutions using to soil and water body of these auxiliary elements.
